Intel® Server Board SDS2

28.OB P100 NICs do not show at POST but attempt PXE boot and appear in Boot Menu

Problem:

On board NIC are not displayed during post but do appear in Boot Device menu.

 

These controllers will also attempt to do a PXE boot if no other bootable devices

 

are found.

Implication:

Not all boot devices displayed during POST when diagnostic display is enabled.

Workaround:

None. This is by design. The system BIOS builds the on-board network

 

controller Option ROM with an option that always makes the OPROM “quiet”. It

 

therefore does not display any text messages and does not allowing the CTRL-

 

S option.

Status:

Will not fix.

29.Dodson: Adaptec 39160 in slots 5 & 6 causes Expansion ROM error

Problem:

Add in Adaptec 39160 Ultra 160 controller installed in slots 5 & 6 causes an

 

Expansion ROM error after last system POST. No other adapters are present.

Implication:

Error message: Expansion ROM not initialized - PCI Mass Storage controller in

 

slot 06. Bus: 02, Device: 09, Function: 01

Workaround:

Adaptec's single image Option ROM requires one 'master' controlling channel

 

that is set using the <Ctrl-A> SCSI Select utility. Each channel loads the Option

 

ROM, determines whether it is the 'master' channel, and if not it unloads

 

completely. If it is the 'master', it proceeds to scan all devices and list all

 

possible drives. Only one channel does this scanning, but ALL channels load

 

the Option ROM initially if the Option ROM is enabled on the slot.

 

The error is coming from the second channel on the Adaptec 39160, even

 

though the first channel has already completed the 'master' scan. The reason it

 

is only happening in Slots 5 and 6 and when the NIC Option ROMs are all

 

loaded is because that is when the available Option ROM space is at a

 

minimum. The NIC Option ROM's are small, but apparently they make enough

 

difference. The onboard 7899 Option ROM loads after Slots 1-4, but before

 

Slots 5 & 6.

 

The solution here is to enable channel B of the ASC39160 as the 'master'

 

channel. When this is done, channel A loads the Option ROM, sees that it is not

 

the 'master', and unloads. Then channel B loads the Option ROM, does the full

 

scan of all devices, and remains in memory. At this point no other channels are

 

found, so no other devices error. The key here is that the LAST available

 

Adaptec channel should be listed as the Master - unfortunately, this is opposite

 

from their default - they default to the first available channel.
